Corrected color components are obtained that correspond to an interpolation between a first and second corrected color component vector, in the first vector the color component are scaled to move a characteristic color component vector towards a target and in the second set the color components are contracted towards a reference determined by part of the color components. A position of the interpolation between the first and second corrected color component vectors is controlled by an interpolation coefficient computed from a ratio of an average value of the at least one of the color component in the input image or one or more reference images with similar content and an average obtained from the other color components of the input image or the or one or more reference images with similar content. The position of the interpolation is moved increasingly toward the second corrected color component vector with decreasing values of said ratio.
